' 191a Serial m1. easiesa To azz whom it may concern:

Be it known that I, BOO-NE SON, a citizen of the United States, residingat St. Louis, Missouri, have invented a certain newtand usefulImprovement in Combined Car-Body Corner-Posts and Door- Frames, ofwhichthe fQllOWiIlg' isga full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and'usethe same, reference being bad to the accompanying drawings,- formingpart of this specification, in

a which #929,705, dated August 3, 1909.11 nds of' car the verticallydis- Figure 1. is a perspective view showing the end of a passengercoach or car in dotted lines with my improved combined cornerpcst anddoor frame applied thereto. Fig.

2 is a horizontal section taken approxif mately on the line 22 of Fig.-1 Fig, is a vertical section taken appr'ognmately on the line 33 ofFig. 1. Fig. 4 is a perspective view of a modifiedform of the combinedcorner post and door frame.

This invention relates generally to railway passenger cars and moreparticularly to the -car end construction, my principal ob:

ject being to provide a simple, strong and comparatively light.one-piece structure whichis preferably castvand which-com-' bines a carbody corner post and door frame.

A further object of my invention is to provide a car end, framereinforcing and bracing member that can be advantageously employedinconnection with all types of car bodies for the purpose'of bracing theupright end frames of the superstructure and materially strengtheningthe ends of the cars, thereby providing a strong, substantial structurewhich willresist severe end shocks due to collisions and resisting alltendency of the cars to telescope, thus af-' fording a maximum degree ofsafety to life and property.

In order to overcome the.tendency of car bodies to telescope duringcollisions various. metal. structures have been, devised a and are atpresent in general use. which structures 'nclude cast metal underframes,platforms,

ailing-sills and one-piece en'd frames which latter structures are'ofthe type shown in- Patents #917,716, dated April 6, 1909 and Tofurtherstrengthen and reinforce. the

V. JoHN- posed end frames applied-thereto so as to reduce toa minimumthe'tendency of said the corner of a car body preferably behind orinside the uprightend-frame. forming a part of said car body, and toform with said post a door frame which occupies a position" between the"corner post and-the end of "the buffer beam.

The combined corner post and door frame I herein shown and described isparticularly designed for use in connection withcombined doublebodybolsters-and platforms of one-piece cast metal end frames of thetype shown in'Patents #917,716 and 929,705;

-' This application isv a division of a'nappli- 1911, Serial after morefully described and claimed.

Referring by numerals to the accompanying drawings; 1 designates the carbody; -2 the underframe, 3 the platform, 4 the-steps '70 the type showniii-Patent #774,474, and the 'sists in certain features of noveltyher'einj at the sides of said platform and 5 theiend frame, all of whichparts are of ordinary well-known construction in the car-'build ers art.

- improved construction as shown com prises an upright or post 6 whichis prefer H ably L-shaped in cross section, and when,

said post is applied for use, the inwardly proJectmg' flange 6" occupiesa position between the upright .end frame at the car inner or rear facesof the side portions of bodv or superstructure and theien-d portions 2said upright car'end frame so as to form an effective brace therefor andto distribute over a considerable area of'the side portions of the endof the car body all end shocks 'sectionand when applied for use the horizontally disposed flange of this rail bears 10cand crushing stresseswhich may be imofthe post 6 is a horizontally disposedrail 7 preferablyof inverted L-shape in, cross directly against the top of the.u'nderframc' 2. Extending from the end of this rail or member 7 to theupper portion of the post or upright 6- is a diagonally disposed brace8. 4

Formed integral;- with. the upper and lower ends ofthe post or uprightGare upper and lower rails 9a1id 10 respectively, which form the linteland threshold plates of the door frame. preferably L-shape incross-section with their horizontally disposed flanges projectinginwardly, and uniting'the outer ends of this lintel vand threshold plateis a vertically disposed post" er upright 11 preferably L-shape in crosssection", and said post or upright is fixed to, forms a substantialupright between the endofthe bufiing sill and'the outer corner of thecar hood.

' The posts 6 and 11 extend below the plane occupied'by the un'derframe2 and platform 3 so that the threshold plate 10 arranged between thelower ends of said posts readily combines "with the "lower one of 'thjecar steps l. Y

In the modified construction illustrated in Fig. 4, a diagonallydisposed bracing member 12 is arranged betweenthe end of the rail 7, andthe centralport-ion of the postor; upright 6 and a diagonally disposedmember 13 is arranged between the end of the. rail 7 and thelower end ofsaid post br upright 6'. v I

My improved reinforcing and-strengthening structure is preferably castin a single piece so that it can be readily applied for use and whenproperly combined with a car body and the upright end fram'e thereof,

said structure provides a yery strong and comparatively lightconstruction which combines with the end frame of ,the car body inresisting all end shocks and stresses due to collisions, therebyminimizing the danger of telescoping of the cars due to collisions whilesaid cars are running at highspeed. w'

The braced corner post '(ibeing positioned to the rear of the car endframe materially strengthens the car end and corner between theunderframe' and the superstructure, and by providing the inwardlyprojecting flanges 6 all stresses and shocks imparted to the upright endframe of the car body are distributed over a considerable area of thecar body superstructure.

In practice, I prefer to form the inwardly projecting flange 6 of thecorner post substantially wider than the side flange, which angmgementis clearly shown in Figs. 1 an 1 The corner postis further bracedagainst crushing stresses and end shocks by the diagonally disposedbracesbetween said corner post and the end of the rail 7,- and thisconstruction combined with the extra wide flange projecting inwardlyfrom the corner Bothof these members are and bottom members.

post is effective in resisting}{crushing stresses which may be imparteddirect to the upright end frame of the car body or superstructure, whichend frame, as shown and described, is preferably arranged so that theinner faces of its side edges bear directly against the wide, inwardlyprojecting flanges 6* of the corner posts.

It will be readily understood that minor changes in the size, form andconstruction of the various parts of my improved reinforcing corner postmay be made and substituted for those herein shown' and describedwithout departing f the Spirit of my invention, the scope'of which is inthe appended claims. r I claim:
